The nature and prevalence of anxiety disorders in primary care

Development and validation of the chronic condition physician-patient relationship scale (CC-PPR): A patient-informed measurement tool

OBJECTIVE

Several tools exist to measure the physician-patient relationship; however few are specific to those with chronic physical health conditions, and none to date have been derived from the patient's perspective. This research aimed to develop and validate a patient-informed tool for measuring the physician-patient relationship with patients who have a chronic physical health condition.

METHODS

Study 1: An Australian sample of participants with a diagnosed chronic physical health condition and a self-reported good physician-patient relationship completed a three round Delphi poll to determine items of the chronic condition physician-patient relationship scale (CC-PPR). Fifty-two participants completed round one, 33 completed round two, and 24 completed all three rounds. Study 2: Exploratory and confirmatory factor analysis were conducted on a separate sample (N = 226) to explore the factor structure of the CC-PPR.

RESULTS

The CC-PPR comprised 22 items within a single-factor structure which demonstrated high internal consistency (Cronbach's α = 0.97) and sound convergent validity.

DISCUSSION

The CC-PPR reliably measures observable, concrete, and specific physician behaviours that patients with chronic physical health conditions believe are critical in forming a good physician-patient relationship. The CC-PPR has potential application in research, educational, and self-assessment contexts, including for the evaluation and development of competence in post-graduate and professional settings.

Curative care expenditure of outpatient anxiety disorder in Liaoning Province, 2015-2020-based on "System of Health Accounts 2011"

Introduction

Anxiety disorders are the most common mental disorder, experienced by more than a quarter of the population. This study examines total outpatient curative care expenditures (CCE) for anxiety disorders and changes in their composition based on the System of Health Accounts 2011 (SHA 2011).

Methods

This study used multi-stage stratified random from a total of 9,318,513 outpatient sample data by 920 healthcare organizations, a total of 109,703 cases of anxiety disorders from 53 sample organizations (5.76%) from 2015 to 2020. Univariate analysis, multifactor analysis and structural equation modeling (SEM) were used to explore the influential factors affecting outpatient CCE for anxiety disorders.

Results

Anxiety disorder outpatient CCE from 2015 to 2020 continued to increase from CNY 99.39million in 2015 to CNY 233.84 million in 2020, mainly concentrated in western medicine costs, 15-64 years, general hospital, generalized anxiety disorder and public financing. The results of univariate analysis showed statistically significant differences in all subgroups, and the results of multivariate analysis and SEM showed that the choice to purchase western drugs, purchase prepared Chinese drugs, choice to have a checkup, urban employees' basic medical insurance, and 0-14 years old were associated with high anxiety disorder outpatient CCE.

Conclusion

Initiatives to improve the essential drug system, reduce the out-of-pocket (OOP) ratio, and strengthen primary health care to effectively reduce the medical burden on patients.

High-level of anxiety and depressive symptoms among patients with general medical conditions and community residents: a comparative study

BACKGROUND

The global burden of anxiety and depressive symptoms become increasing, specifically accounts for high burden of morbidity among patients with medical conditions in low-income countries. The aim was to compare the level of anxiety and depressive symptoms in participants with general medical conditions and community residents in northwest Ethiopia.

METHODS

Comparatively 2625 adults in the community and 1363 patients at health center in Mecha Demographic Surveillance and Field Research Center (MDSFRC) had interviewed. Level of anxiety and depressive symptoms was assessed by Hospital Anxiety and Depression Scale (HADS) and logistic regression analysis was employed with corresponding adjusted OR (AOR) and 95% confidence interval (CI) at p-value less than 0.05 declaration of significant.

RESULTS

A higher prevalence of high-level anxiety and depressive symptoms, 12.6% with 95% CI; 11.0%, 14.0% and 10.1%, 95% CI; 8.0%, 12% were found among participants at health center compared to community residents, 6.8%, 95% CI; 7.0%, 8.0% and 5.2%, 95% CI; 4.0%, 6.0% at (p value < .0001), respectively. Social support, loss of a parent before age of 18 years, physical/verbal abuse, and having general medical conditions were significantly associated with both high-level anxiety and depressive symptoms. However, factors such as advanced age, perceived relative wealth, living alone, and having a family history of mental illness were associated with high-level of anxiety symptoms, but not with depressive symptoms.

CONCLUSIONS

Proportion of high-level of anxiety and depressive symptoms were found a two-fold higher in patients with medical condition than healthy residents in the community. Patients with medical illnesses should be assess for anxiety and depressive symptoms at health center.

Retrospective Analyses of Psychological Distress and Defense Style Among Cancer Patients

OBJECTIVE

Psychological distress is common in cancer patients during the diagnostic phase. Research demonstrated that anxiety, depression and defense mechanisms may influence physical and psychological well-being in patients with malignant tumors. The present retrospective study investigated the associations between clinical and psychological characteristics of cancer patients waiting for the diagnosis, focusing on metastatic cancer (MC) and breast cancer (BC).

METHOD

Patients with a new diagnosis of cancer referring to a Clinical Oncology Unit in Central Italy were interviewed during the 2017 for psychological assessment. Double-blind information about anxiety, depression, sleep disorders, defense style, and cancer diagnosis were available for the 567 patients included in this study. T-test, chi-squared and regression analyses were performed to detect associations between psychological variables and the presence of metastasis (MC) in the whole sample and in the subgroup of breast cancer (BC) patients.

RESULTS

Female gender and younger age were associated with anxiety, depression, and maladaptive defense style. A significant positive relationship was found between presence of metastasis and symptoms of anxiety. Depression resulted significantly more frequent in BC, while there was a trend close to statistical significance in MC. Immature defense style was widely used by BC women, with a score close to statistical significance.

CONCLUSIONS

This retrospective study provided empirical evidence of the relationship between psychological functioning and clinical characteristics of cancer. In line with previous research, our findings confirmed the peculiar psychological functioning of BC patients. Further investigations are needed to understand how the diagnosis of cancer may influence the individual psychological functioning and vice versa.

Optimal primary care management of clinical osteoarthritis and joint pain in older people: a mixed-methods programme of systematic reviews, observational and qualitative studies, and randomised controlled trials

Background

Osteoarthritis (OA) is the most common long-term condition managed in UK general practice. However, care is suboptimal despite evidence that primary care and community-based interventions can reduce OA pain and disability.

Objectives

The overall aim was to improve primary care management of OA and the health of patients with OA. Four parallel linked workstreams aimed to (1) develop a health economic decision model for estimating the potential for cost-effective delivery of primary care OA interventions to improve population health, (2) develop and evaluate new health-care models for delivery of core treatments and support for self-management among primary care consulters with OA, and to investigate prioritisation and implementation of OA care among the public, patients, doctors, health-care professionals and NHS trusts, (3) determine the effectiveness of strategies to optimise specific components of core OA treatment using the example of exercise and (4) investigate the effect of interventions to tackle barriers to core OA treatment, using the example of comorbid anxiety and depression in persons with OA.

Data sources

The North Staffordshire Osteoarthritis Project database, held by Keele University, was the source of data for secondary analyses in workstream 1.

Methods

Workstream 1 used meta-analysis and synthesis of published evidence about effectiveness of primary care treatments, combined with secondary analysis of existing longitudinal population-based cohort data, to identify predictors of poor long-term outcome (prognostic factors) and design a health economic decision model to estimate cost-effectiveness of different hypothetical strategies for implementing optimal primary care for patients with OA. Workstream 2 used mixed methods to (1) develop and test a ‘model OA consultation’ for primary care health-care professionals (qualitative interviews, consensus, training and evaluation) and (2) evaluate the combined effect of a computerised ‘pop-up’ guideline for general practitioners (GPs) in the consultation and implementing the model OA consultation on practice and patient outcomes (parallel group intervention study). Workstream 3 developed and investigated in a randomised controlled trial (RCT) how to optimise the effect of exercise in persons with knee OA by tailoring it to the individual and improving adherence. Workstream 4 developed and investigated in a cluster RCT the extent to which screening patients for comorbid anxiety and depression can improve OA outcomes. Public and patient involvement included proposal development, project steering and analysis. An OA forum involved public, patient, health professional, social care and researcher representatives to debate the results and formulate proposals for wider implementation and dissemination.

Results

This programme provides evidence (1) that economic modelling can be used in OA to extrapolate findings of cost-effectiveness beyond the short-term outcomes of clinical trials, (2) about ways of implementing support for self-management and models of optimal primary care informed by National Institute for Health and Care Excellence recommendations, including the beneficial effects of training in a model OA consultation on GP behaviour and of pop-up screens in GP consultations on the quality of prescribing, (3) against adding enhanced interventions to current effective physiotherapy-led exercise for knee OA and (4) against screening for anxiety and depression in patients with musculoskeletal pain as an addition to current best practice for OA.

Conclusions

Implementation of evidence-based care for patients with OA is feasible in general practice and has an immediate impact on improving the quality of care delivered to patients. However, improved levels of quality of care, changes to current best practice physiotherapy and successful introduction of psychological screening, as achieved by this programme, did not substantially reduce patients’ pain and disability. This poses important challenges for clinical practice and OA research.

Limitations

The key limitation in this work is the lack of improvement in patient-reported pain and disability despite clear evidence of enhanced delivery of evidence-based care.

Future work recommendations

(1) New thinking and research is needed into the achievable and desirable long-term goals of care for people with OA, (2) continuing investigation into the resources needed to properly implement clinical guidelines for management of OA as a long-term condition, such as regular monitoring to maintain exercise and physical activity and (3) new research to identify subgroups of patients with OA as a basis for stratified primary care including (i) those with good prognosis who can self-manage with minimal investigation or specialist treatment, (ii) those who will respond to, and benefit from, specific interventions in primary care, such as physiotherapy-led exercise, and (iii) develop research into effective identification and treatment of clinically important anxiety and depression in patients with OA and into the effects of pain management on psychological outcomes in patients with OA.

Screening and correlates of neurotic disorders among general medical outpatients in Xi'an China

PURPOSE

Little is known about the distribution and correlates of neurotic disorders among general medical outpatients. The aim was to identify the population distribution and associated factors of neurotic disorders among general medical outpatients.

DESIGN AND METHODS

A cross-sectional design was used. Computer-assisted interviews of 372 general outpatients aged 16 years or older in Xi'an China were conducted using a Chinese version of the World Health Organization Composite International Diagnostic Interview version 3.0 (CIDI-3.0).

FINDINGS

The estimated lifetime prevalence of any ICD-10 neurotic disorder among general medical outpatients was 10.8%. The most prevalent subtype of neurotic disorders was specific phobias (5.7%) followed by obsessive-compulsive disorders (3.8%) and social phobias (1.3%). General outpatients who visited the department of internal medicine (OR = 6.55, 95% CI 1.51-28.38), who were under 40 years old (OR = 4.44, 95% CI 2.05-9.62), had less than high school education (OR = 4.19, 95% CI 1.79-9.79), and were female (OR = 2.25, 95% CI 1.14-4.47) were most likely to report neurotic disorders.

PRACTICE IMPLICATIONS

Effective identification of neurotic disorders is crucial for its early detection and targeted intervention among general medical outpatients. Those outpatients who had younger age and lower education level, and were female and had visited internal medicine departments require additional attention.

Prevention of anxiety and depression in Chinese: a randomized clinical trial testing the effectiveness of a stepped care program in primary care

BACKGROUND

Despite empirical evidence demonstrating the effectiveness of collaborative stepped care program (SCP) in Western countries, such programs have not been evaluated in the east, which has a different services system structure and cultural nuances in seeking help for mental illness. Furthermore, only a few studies have used SCP for depression and anxiety prevention. We conducted a trial to test its effectiveness in preventing major depressive disorder and generalized anxiety disorder among primary care patients with subthreshold depression and/or anxiety in Hong Kong.

METHODS

Subthreshold depression and/or anxiety patients were randomized into the SCP group (n=121) or care as usual (CAU) group (n=119). The SCP included watchful waiting, telephone counseling, problem solving therapy, and family doctor treatment within one year. The primary outcome was the onset of major depressive disorder or generalized anxiety disorder in 15 months. The secondary outcomes were depressive and anxiety symptoms, quality of life and time absent from work due to any illness.

RESULTS

Survival analysis showed no differences between the SCP and CAU groups (the cumulative probability of onset at 15 month was 23.1% in the SCP group and 20.5% in the CAU group; Hazard Ratio=1.62; 95% Confidence Interval: 0.82-3.18; p=0.16). No significant differences were found in secondary outcomes.

LIMITATIONS

Sample size might not have been large enough.

CONCLUSIONS

SCP did not show beneficial effect on depression/anxiety prevention compared with CAU in Hong Kong primary care. As a large majority of patients improved overtime without any intervention, we are not able to exclude the possibility that the intervention might be effective. Future studies would need to have a larger sample size and conduct on patients with more severe symptoms or perform a second screening.

Neurotic disorders of general medical outpatients in Xi'an, China: knowledge, attitudes, and help-seeking preferences

OBJECTIVE

This study assessed knowledge of neurotic disorders, and attitudes and preferences toward professional help and treatment for them, among general medical outpatients in general hospitals in Xi'an, China.

METHODS

General medical outpatients (N=372) from general hospitals in China were recruited by using a stratified cluster sampling method between June and September 2010. In face-to-face interviews, participants age 16 years or older were assessed for their knowledge, attitudes, and help-seeking preferences in regard to neurotic disorders (obsessive-compulsive disorder, social phobia, and panic disorder). Demographic data were also collected.

RESULTS

Lack of insight into neurotic disorders was common among medical outpatients in general hospitals of Xi'an, China. Twenty-four percent to 58% of the outpatients had some knowledge of the symptoms and treatment of neurotic disorders. Only 11% of the outpatients would reveal to others that they or a family member suffered from neurotic disorders. When faced with the problem of neurotic disorders, the preference of the respondents was to visit a psychiatrist in a general hospital (44%), and only 17% would visit a physician in a psychiatric hospital. Major ways for the outpatients to obtain knowledge regarding neurotic disorders were via radio and television (36%), and only 18%-23% of outpatients obtained knowledge about neurotic disorders through printed public health materials and by attending lectures.

CONCLUSIONS

Study results underscore the need for information campaigns aimed at improving the mental health literacy of general medical outpatients. Such campaigns must consider culturally relevant beliefs to facilitate the development of specific educational programs.

Adequacy of treatment received by primary care patients with anxiety disorders

BACKGROUND

We examined the adequacy of pharmacotherapy and psychotherapy received by primary care patients with anxiety disorders over up to 5 years of follow-up.

METHOD

Five hundred thirty-four primary care patients at 15 US sites, who screened positive for anxiety symptoms, were assessed for anxiety disorders. Those meeting anxiety disorder criteria were offered participation and interviewed again at six and 12 months postintake, and yearly thereafter for up to 5 years. We utilized existing definitions of appropriate pharmacotherapy and created definitions of potentially adequate psychotherapy/cognitive-behavioral therapy (CBT).

RESULTS

At intake, of 534 primary care participants with anxiety disorders, 19% reported receiving appropriate pharmacotherapy and 14% potentially adequate CBT. Overall, 28% of participants reported receiving potentially adequate anxiety treatment, whether pharmacotherapy, psychotherapy, or both. Over up to five years of follow-up, appropriate pharmacotherapy was received by 60% and potentially adequate CBT by 36% of the sample. Examined together, 69% of participants received any potentially adequate treatment during the follow-up period. Over the course of follow-up, primary care patients with MDD, panic disorder with agoraphobia, and with medicaid/medicare were more likely to receive appropriate anxiety treatment. Ethnic minority members were less likely to receive potentially adequate care.

CONCLUSIONS

Potentially adequate anxiety treatment was rarely received by primary care patients with anxiety disorders at intake. Encouragingly, rates improved over the course of the study. However, potentially adequate CBT remained much less utilized than pharmacotherapy and racial-ethnic minority members were less likely to received care, suggesting much room for improved dissemination of quality treatment.

Recognition of anxiety disorders by family physicians after rigorous medical record case extraction: results of the Netherlands Study of Depression and Anxiety

OBJECTIVE

Previous studies reported low and inconsistent rates of recognition of anxiety disorders by family physicians (FPs). Our objectives were to examine (a) which combination of indications within medical records most accurately reflects recognition of anxiety disorders and (b) whether patient and FP characteristics were related to recognition.

METHOD

A cross-sectional comparison was made between FPs' registration and a structured diagnostic interview, the Composite International Diagnostic Interview, according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. Seven definitions of recognition were tested using diagnostic codes, medication data, referral data and free text in medical records. Data were derived from the Netherlands Study of Depression and Anxiety. A total of 816 patients were included.

RESULTS

Recognition ranged between 9.1% and 85.8%. A broader definition was associated with a higher recognition rate, but led to more false positives. The best definition comprised diagnostic codes for anxiety disorders and symptoms, strong free-text indications, medication and referral to mental health care. Generalized anxiety disorder was best recognized by this definition. Recognition was better among patients with increased severity, comorbid depression and older age.

CONCLUSION

FPs recognized anxiety disorders better than previously reported when all medical record data were taken into account. However, most patients were nonspecifically labeled as having a mental health problem.

Anxiety and depression, chronic physical conditions, and quality of life in an urban population sample study

OBJECTIVE

No previous studies have empirically demonstrated a multiplicative interactive effect of anxiety disorders and/or depression (ADD) and chronic medical conditions on quality of life (QOL). We hypothesized that QOL impairment was worsened by the presence of ADD and medical co-morbidity, more than when it was with either medical co-morbidity alone or ADD alone.

METHODS

Complete data of 2,801 participants from the National Mental Health Survey of Adults in Singapore were analyzed, using SCAN diagnoses of anxiety disorders and depression, self-reports of chronic medical conditions, and SF-12 measures of QOL (Mental Component Summary, MCS, and Physical Component Summary, PCS).

RESULTS

Persons diagnosed with ADD (compared to those without) had considerably more medical co-morbidities (59 vs. 33%, p < 0.001). In multiple regression analyses, ADD (vs. no ADD) was associated with lower PCS (b = -1.013, p = 0.045) and MCS scores (b = -9.912, p < 0.001), as was number of medical co-morbidities (0, 1-2, 3 +), PCS scores (b = -2.058, p < 0.001) and MCS scores (b = -1.138, p < 0.001). There were significant interactive effects of medical co-morbidities and ADD on PCS (p < 0.001), and MCS (p = 0.086), suggesting that the negative effects of medical conditions on quality of life was aggravated non-additively by the co-morbid presence of ADD, and vice versa.

CONCLUSION

The individual effects of medical and psychiatric morbidity on functional status and quality of life were considerably worse when both were present in the same individual. Future studies should examine the impact of identifying and treating anxiety and depressive disorders in patients with medical problems for better outcomes.

A randomized, controlled clinical trial: the effect of mindfulness-based cognitive therapy on generalized anxiety disorder among Chinese community patients: protocol for a randomized trial

BACKGROUND

Research suggests that an eight-week Mindfulness-Based Cognitive Therapy (MBCT) program may be effective in the treatment of generalized anxiety disorders. Our objective is to compare the clinical effectiveness of the MBCT program with a psycho-education programme and usual care in reducing anxiety symptoms in people suffering from generalized anxiety disorder.

METHODS

A three armed randomized, controlled clinical trial including 9-month post-treatment follow-up is proposed. Participants screened positive using the Structure Clinical Interview for DSM-IV (SCID) for general anxiety disorder will be recruited from community-based clinics. 228 participants will be randomly allocated to the MBCT program plus usual care, psycho-education program plus usual care or the usual care group. Validated Chinese version of instruments measuring anxiety and worry symptoms, depression, quality of life and health service utilization will be used. Our primary end point is the change of anxiety and worry score (Beck Anxiety Inventory and Penn State Worry Scale) from baseline to the end of intervention. For primary analyses, treatment outcomes will be assessed by ANCOVA, with change in anxiety score as the baseline variable, while the baseline anxiety score and other baseline characteristics that significantly differ between groups will serve as covariates.

CONCLUSIONS

This is a first randomized controlled trial that compare the effectiveness of MBCT with an active control, findings will advance current knowledge in the management of GAD and the way that group intervention can be delivered and inform future research.

Impairment and functioning in a sample of primary care patients with generalized anxiety disorder: results from the primary care anxiety project

OBJECTIVE

To examine the extent of functional impairment associated with generalized anxiety disorder (GAD) in a sample of primary care patients.

METHOD

Participants (N = 128) were part of the Primary Care Anxiety Project (PCAP), a study conducted in 15 primary care practices in the northeastern United States. Patients were recruited in primary care practice waiting rooms from July 1997 to May 2001. Participants screening positive for anxiety symptoms received a diagnostic interview and an assessment of health-related functioning (Medical Outcomes Study 36-item Short-Form Health Survey [SF-36]). Effect sizes are reported for comparisons of SF-36 scores between patients with a DSM-IV diagnosis of GAD and general population and medical sample norms.

RESULTS

Relative to general population normative SF-36 scores, primary care patients with GAD evidenced impaired functioning on both the physical and mental component summary scales. Patients with GAD also evidenced greater impairment in psychosocial functioning than that previously reported for samples of patients with major medical illnesses, including type II diabetes, hypertension, recent myocardial infarction, and congestive heart failure. This finding held true even when GAD patients with comorbid medical illnesses and comorbid Axis I mental disorders were excluded from the comparison.

CONCLUSIONS

Primary care patients with GAD experience substantial impairment that cannot be accounted for by concurrent medical illnesses or comorbid Axis I mental disorders.

Prevalence of anxiety among women attending a primary care clinic in Malaysia

BACKGROUND

This is the first study investigating anxiety among women attending a primary care clinic in Malaysia.

AIM

The objective was to determine the factors associated with anxiety among these women.

DESIGN

This cross-sectional study was conducted in a government-funded primary care clinic in Malaysia. Consecutive female patients attending the clinic during the data-collection period were invited to participate in the study.

METHOD

Participants were given self-administered questionnaires, which included the validated Generalised Anxiety Disorder-7 questionnaire (GAD-7) Malay version to detect anxiety.

RESULTS

Of the 1023 patients who were invited, 895 agreed to participate (response rate 87.5%). The prevalence of anxiety in this study was 7.8%, based on the GAD-7 (score ≥8). Multiple logistic regression analysis found that certain stressful life events and the emotional aspect of domestic violence were significantly associated with anxiety (P<0.05).

CONCLUSION

The prevalence of anxiety among women in this study is similar to that found in other countries. Factors found to be associated with anxiety, especially issues on domestic violence, need to be addressed and managed appropriately.

Anxiety, depression, and quality of life in primary care patients

BACKGROUND

Anxiety and depressive disorders have a significant and negative impact on quality of life. However, less is known about the effects of anxiety and depressive symptoms on quality of life. The purpose of this study was to examine the impact of anxiety and depressive symptoms on emotional and physical functioning, the effects of anxiety symptoms on functioning independent of depressive symptoms, and the effects of depressive symptoms on functioning independent of anxiety symptoms.

METHOD

Participants included 919 patients, recruited from 2 university-affiliated primary care clinics between May 2004 and September 2006, who completed self-report measures of anxiety symptoms, depressive symptoms, and quality of life.

RESULTS

Almost 40% of the sample reported anxiety symptoms and 30% reported depressive symptoms. In both unadjusted and adjusted models, anxiety and depressive symptoms were significantly associated with all domains of quality of life. When anxiety and depressive symptoms were added simultaneously, both remained significant. As the severity of anxiety or depressive symptoms increased, quality of life decreased. Furthermore, patients with moderate to severe anxiety or depressive symptoms had greater impairments in most quality of life domains than patients with acute myocardial infarction, congestive heart failure, or diabetes.

CONCLUSION

Detection and treatment of anxiety and depressive symptoms in the primary care setting should be emphasized.

Psychometrics of a brief measure of anxiety to detect severity and impairment: the Overall Anxiety Severity and Impairment Scale (OASIS)

Brief measures of anxiety-related severity and impairment that can be used across anxiety disorders and with subsyndromal anxiety are lacking. The Overall Anxiety Severity and Impairment Scale (OASIS) have shown strong psychometric properties with college students and primary care patients. This study examines sensitivity, specificity, and efficiency of an abbreviated version of the OASIS that takes only 2-3 min to complete using a non-clinical (college student) sample. 48 participants completed the OASIS and SCID for anxiety disorders, 21 had a diagnosis of ≥1 anxiety disorder, and 4 additional participants had a subthreshold diagnosis. A cut-score of 8 best discriminated those with anxiety disorders from those without, successfully classifying 78% of the sample with 69% sensitivity and 74% specificity. Results from a larger sample (n = 171) showed a single factor structure and excellent convergent and divergent validity. The availability of cut-scores for a non-clinical sample furthers the utility of this measure for settings where screening or brief assessment of anxiety is needed.

Recognizing and managing anxiety disorders in primary health care in Turkey

Background

Anxiety disorders are common and are frequently not diagnosed accurately in primary care. Our aim was to determine the knowledge gaps of general practitioners (GPs) in the diagnosis and treatment of anxiety disorders by using vignettes.

Methods

A cross-sectional survey was completed with 255 primary care physicians (response rate 59.4%) in Manisa, a city in western Turkey. From the postal questionnaire, information on working experience, postgraduate education in psychiatry, the interests of the physicians in psychiatry were obtained. The physicians' diagnosis and treatment preferences for generalized anxiety disorder (GAD), social phobia (SP), and obsessive compulsive disorder (OCD) were determined through clinical vignettes prepared for data collection.

Results

Two hundred and twenty-seven (89.0%) out of 255 GPs included the diagnosis of obsessive compulsive disorder in their differential diagnosis; however, the rates for social phobia and generalized anxiety disorder were 69.4% (n = 177) and 22.3% (n = 57), respectively. GPs with a post-graduate education on psychiatry diagnosed vignettes more accurately for OCD (p = 0.04). For all three cases, GPs mostly preferred a combination therapy including psychotherapy and psycho-pharmacotherapy. The referral rate to a psychiatrist was between 23.1 and 30.6%. The percentages of the prescription of selective serotonin reuptake inhibitors (SSRI) in accurate diagnosis were 59.3 for social phobia, 33.3 for GAD, and 55.5 for OCD.

Conclusions

There is a gap of knowledge in GPs, which leads to poor recognition and management of anxiety disorders in primary care. Effective interventions including post-graduate education and updated guidelines on anxiety disorders should be planned and implemented with their assessments by vignettes.

Prevalence and rates of recognition of anxiety disorders in internal medicine outpatient departments of 23 general hospitals in Shenyang, China

OBJECTIVE

Assess the prevalence, risk factors and treating clinicians' rates of recognition of anxiety disorders in internal medicine departments of different types of general hospitals in Shenyang, China.

METHOD

A two-stage screening process using an expanded Chinese version of the 12-item General Health Questionnaire (GHQ) and the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID) identified 457 persons 15 years of age or older with current anxiety disorders from among 5312 consecutive attendees at the outpatient internal medicine departments of 23 randomly selected general hospitals. Clinical charts were reviewed to determine whether or not the treating internist had made a diagnosis of anxiety or prescribed anxiolytic medications.

RESULTS

The 1-month prevalence of any type of anxiety disorder was 9.8% (95% CI=9.0-10.8%). The prevalences of the three most common disorders: anxiety disorder not otherwise specified, generalized anxiety disorder and anxiety disorder due to a general medical condition, were 6.3% (5.6-7.1%), 2.4% (2.0-2.9%), and 0.6% (0.4-0.8%), respectively. Multivariate logistic regression analysis identified the following independent predictors of having a current anxiety disorder: every being married (OR=3.5, 95% CI=2.3-5.4), prior treatment for psychological problems (3.3, 1.8-6.0), having religious beliefs (1.9, 1.3-2.9), low family income (1.5, 1.2-1.9) and never having attended college (1.3, 1.02-1.8). Among the 402 patients with anxiety disorders for whom the clinical chart was reviewed only 16 (4.0%, CI=2.3-6.3%) were diagnosed with an anxiety condition or treated with anxiolytic medications.

CONCLUSION

The prevalence of anxiety in internal medicine outpatients in urban China is lower than that reported in most western countries and the profile of risk factors is somewhat different. The very low rate of recognition of these disorders by internists is related both to the low rates of care-seeking for psychological problems in the general population and to the high-volume collective model of care delivery in the outpatient departments of Chinese general hospitals. Steps to increase the recognition and treatment of anxiety disorders in Chinese general hospitals must focus both on changing attitudes of patients and clinicians and, more importantly, on altering the structure of care delivery.

Brief intervention for anxiety in primary care patients

To address the difficulty of assessing and managing multiple anxiety disorders in the primary care setting, this article provides a simple, easy-to-learn, unified approach to the diagnosis, care management, and pharmacotherapy of the 4 most common anxiety disorders found in primary care: panic, generalized anxiety disorders, social anxiety disorders, and posttraumatic stress disorder. This evidence-based approach was developed for an ongoing National Institute of Mental Health-funded study designed to improve the delivery of evidence-based medication and psychotherapy treatment to primary care patients with these anxiety disorders. We present a simple, validated method to screen for the 4 major disorders that emphasizes identifying other medical or psychiatric comorbidities that can complicate treatment; an approach for initial education of the patient and discussion about treatment, including provision of some simple cognitive behavioral therapy skills, based on motivational interviewing/brief intervention approaches previously used for substance use disorders; a validated method for monitoring treatment outcome; and an algorithmic approach for the selection of initial medication treatment, the selection of alternative or adjunctive treatments when the initial approach has not produced optimal results, and indications for mental health referral.

How do general practitioners in Thailand diagnose and treat patients presenting with anxiety and depression?

AIMS

To examine general practitioners' (GPs') diagnosis of a case vignette presenting both anxiety and depression symptoms, and to understand their treatment preferences for the case.

METHODS

A total of 1193 copies of a questionnaire were sent to doctors in primary care settings throughout Thailand. The questionnaire inquired about GPs' demographic information and training background, as well as common psychiatric diagnoses and drug prescriptions to patients in their practise. A case vignette of a patient presenting both anxiety and depression symptoms was then given, and GPs were asked to describe their diagnosis and treatment preferences. For comparison, postal questionnaires of the same case vignette were also sent to 40 psychiatrists practising in general hospitals, asking their opinion about the diagnosis and treatment preferences.

RESULTS

A total of 434 questionnaires (36.4%) were returned. GPs reported that 37.7% of their patients suffered from anxiety disorders while 28.4% suffered from depressive disorders. For the patient in the case vignette, GPs made a diagnosis of anxiety disorders (53.5%) more often than depressive disorders (31.9%), whereas the psychiatrists at the general hospitals made a diagnosis of depressive disorders (54%) more often than anxiety disorders (9.1%). One-third of the GPs prescribed only anxiolytics, while 15.4% prescribed only antidepressants. The most commonly prescribed antidepressant by GPs was amitriptyline, which 93% of GPs used at a dosage below 50 mg/day. Only 5.8% of them prescribed fluoxetine as antidepressant. The most frequently prescribed anxiolytic drug was diazepam (65.4%). The most common combination of drugs prescribed was amitriptyline and diazepam (38.7%).

CONCLUSION

Compared to psychiatrists, GPs were more likely to diagnose anxiety than depression in patients with the same set of symptoms. They also preferred to use amitriptyline to treat depression, and prescribed the drug at a low dose. GPs in Thailand should be encouraged to prescribe fluoxetine for treatment of depression because it is safer and more convenient to use than tricyclic antidepressants.

Impact of demographic factors on recognition of persons with depression and anxiety in primary care in Slovenia

BACKGROUND

Research has repeatedly shown that family physicians fail to diagnose up to 70% of patients with common mental disorders. Objective of the study is to investigate associations between persons' gender, age and educational level and detection of depression and anxiety by their family physicians.

METHODS

We compared the results of two independent observational studies that were performed at the same time on a representative sample of family medicine practice attendees in Slovenia. 10710 patients participated in Slovenian Cross-sectional survey and 1118 patients participated in a first round of a cohort study (PREDICT-D study). Logistic regression was used to examine the effects of age, gender and educational level on detection of depression and anxiety.

RESULTS

The prevalence of major depression and Other Anxiety Syndrome (OAS) amongst family practice attendees was low. The prevalence of Panic Syndrome (PS) was comparable to rates reported in the literature. A statistical model with merged data from both studies showed that it was over 15 times more likely for patients with ICD-10 criteria depression to be detected in PREDICT-D study as in SCS survey. In PREDICT-D study it was more likely for people with higher education to be diagnosed with ICD-10 criteria depression than in SCS survey.

CONCLUSION

People with higher levels of education should probably be interviewed in a more standardized way to be recognised as having depression by Slovenian family physicians. This finding requires further validation.

A new case-finding tool for anxiety: a pragmatic diagnostic validity study in primary care

OBJECTIVE

Anxiety is common in the community and in family practice (FP) patients. It is a treatable condition but often not diagnosed. The aim of this study was to determine the validity of two written questions to aid family physicians in the identification of anxiety. The first question asks the patient whether they have been worrying a lot during the past month; and the second question asks whether the patient would like help with this problem.

METHODS

The study was a pragmatic cross sectional validity study conducted with 19 family physicians in six clinics in New Zealand. The outcomes were the sensitivity, specificity, and likelihood ratios compared with the HADS anxiety score > or = 11 as a gold standard.

RESULTS

The study recruited 982 consecutive patients receiving no psychotropic drugs. The FP diagnosis had a sensitivity of 58% (95% CI 45% to 69%) and a specificity of 87% (95% CI 85 to 89). The worry question alone had a sensitivity of 76% (95% CI 64% to 85%) and a specificity of 82% (95% CI 79% to 84%). The positive likelihood ratio for patients wanting help today was 9.29 (95% CI 5.62 to 15.36). The likelihood ratio for patients worrying but not wanting help was 2.29 (95% CI 1.48 to 3.55). The likelihood ratio (negative) for those not worrying was 0.29 (95% CI 0.18 to 0.46).

CONCLUSIONS

The use of a case-finding question for anxiety and a question asking whether help is wanted increases the positive likelihood ratio indicating that the use of the two questions may aid family physicians in identifying cases of anxiety.

Screening for depression and anxiety disorders in primary care patients

Mood and anxiety disorders are highly prevalent in primary health care. In this study we assessed performance of the Hospital Anxiety and Depression Scale (HADS) for screening of depression and anxiety disorders in a population of primary care patients. A total of 503 primary care patients consecutively admitted to the primary care medical center in Kaunas, Lithuania, completed the study. We found that the HADS subscale of depression (HADS-D) at a cutoff score of 6 or more showed the best performance screening for a major depressive episode diagnosed by means of the Mini International Neuropsychiatric Interview (MINI), with a sensitivity of 80%, specificity of 69%, positive predictive value of 80%, negative predictive value of 92%, and area under the receiver operating characteristic (ROC) curve of 0.75. Performance of the HADS-D against MINI diagnosis of dysthymia was weak. The HADS subscale of anxiety (HADS-A) at a cutoff score of 9 or more showed the best performance screening for MINI diagnosis of overall anxiety disorders, with a sensitivity of 77%, specificity of 75%, positive predictive value of 53%, negative predictive value of 90%, and area under the ROC curve of 0.76. These results suggest that in primary care patients HADS is an adequate screening instrument for the MINI diagnoses of major depressive episode, but not for dysthymia at a cutoff score of 6, and for anxiety disorders at a cutoff score of 9.

Psychiatric treatment in primary care patients with anxiety disorders: a comparison of care received from primary care providers and psychiatrists

OBJECTIVE

This study examined psychiatric treatment received by primary care patients with anxiety disorders and compared treatment received from primary care physicians and from psychiatrists.

METHOD

Primary care patients at 15 sites were screened for anxiety symptoms. Those screening positive were interviewed to assess for anxiety disorders. Information on psychiatric treatment received and provider of pharmacological treatment were collected.

RESULTS

Of 539 primary care participants with at least one anxiety disorder, almost half (47.3%) were untreated. Nearly 21% were receiving medication only for psychiatric problems, 7.2% were receiving psychotherapy alone, and 24.5% were receiving both medication and psychotherapy. Patients receiving psychopharmacological treatment received similar medications, often at similar dosages, regardless of whether their prescriber was a primary care physician or a psychiatrist. One exception was that patients were less likely to be taking benzodiazepines if their provider was a primary care physician. Those receiving medications from a primary care provider were also less likely to be receiving psychotherapy. Overall, patients with more functional impairment, more severe symptoms, and comorbid major depression were more likely to receive mental health treatment. Members of racial/ethnic minority groups were less likely to be treated. Frequently endorsed reasons for not receiving pharmacological treatment were that the primary care physician did not recommend it and the patient did not believe in taking medication for emotional problems.

CONCLUSIONS

Nearly half the primary care patients with anxiety disorders were not treated. However, when they were treated, the care received from primary care physicians and psychiatrists was relatively similar.

Development and validation of an Overall Anxiety Severity And Impairment Scale (OASIS)

Establishing severity and impairment associated with anxiety is important in many settings. We developed a brief (five-item) continuous measure, the Overall Anxiety Severity and Impairment Scale (OASIS), which can be used across anxiety disorders, with multiple anxiety disorders, and with subthreshold anxiety symptoms. Seven hundred eleven college students completed the OASIS and additional self-report assessments of anxiety-related concerns and symptoms. A subset of students completed several measures again 1 month later. Results of a split-sample analysis suggested a single-factor structure, with all five items having salient loadings. The OASIS demonstrated excellent 1-month test-retest reliability, and convergent and divergent validity. The OASIS merits consideration as a brief measure of anxiety-related severity and impairment that can be used across anxiety disorders.

The utility of somatic symptoms as indicators of depression and anxiety in military veterans with chronic obstructive pulmonary disease

The interrelationship between medical illnesses and psychological distress has received increasing attention in the last several years. Partly at issue is the best way to diagnose mental health problems such as depression and anxiety in medical populations. Specifically, are somatic symptoms a valid indicator of depression and anxiety in a medical population? Furthermore, do anxiety and depression remain as distinct constructs for this population, or do they combine to represent general distress? We examine these issues using confirmatory factor analysis in a sample of 202 military veterans with chronic obstructive pulmonary disease. Results indicate best fit for a model of depression and anxiety for which the constructs remained separate rather than as combined indicators of general distress. Furthermore, in this model, somatic symptoms are retained as valid indicators of psychological distress for this sample.

Characteristics and predictors of full and partial recovery from generalized anxiety disorder in primary care patients

The current study examined the naturalistic course of generalized anxiety disorder (GAD) in a sample of 113 primary care patients across a 2-year period. Initial diagnoses were established using structured clinical interviews according to DSM-IV diagnostic criteria. Results indicated that the majority of patients meeting DSM-IV diagnostic criteria for GAD were still symptomatic to some degree after 2 years of follow-up. Rates of full and partial recovery from GAD, however, were found to be higher than those reported for previous studies of GAD in psychiatric patients. Diagnostic comorbidity, severity of psychosocial impairment, and gender were found to be significantly associated with achieving full or partial recovery from GAD. Psychiatric treatment was not found to be associated with time to full or partial recovery from GAD symptoms, likely due to a treatment-biasing effect. These results underscore that GAD is a chronic and persistent illness in primary care patients.

Functional Impact and Health Utility of Anxiety Disorders in Primary Care Outpatients

OBJECTIVE

The objective of this study was to examine the relative impact of anxiety disorders and major depression on functional status and health-related quality of life of primary care outpatients.

METHOD

Four hundred eighty adult outpatients at an index visit to their primary care provider were classified by structured diagnostic interview as having anxiety disorders (panic disorder with or without agoraphobia, social phobia, and posttraumatic stress disorder; generalized anxiety disorder was also assessed in a subset) with or without major depression. Functional status, sick days from work, and health-related quality of life (including a preference-based measure) were assessed using standardized measures adjusting for the impact of comorbid medical illnesses. Relative impact of the various anxiety disorders and major depression on these indices was evaluated.

RESULTS

In multivariate regression analyses simultaneously adjusting for age, sex, number of chronic medical conditions, education, and/or poverty status, each of major depression, panic disorder, posttraumatic stress disorder, and social phobia contributed independently and relatively equally to the prediction of disability and functional outcomes. Generalized anxiety disorder had relatively little impact on these indices when the effects of comorbid major depression were considered. Overall, anxiety disorders were associated with substantial decrements in preference-based health states.

CONCLUSIONS

These observations demonstrate that the presence of each of 3 common anxiety disorders (ie, panic disorder, posttraumatic stress disorder, and social phobia)-over and above the impact of chronic physical illness, major depression, and other socioeconomic factors-contributes in an approximately additive fashion to the prediction of poor functioning, reduced health-related quality of life, and more sick days from work. Greater awareness of the deleterious impact of anxiety disorders in primary care is warranted.

Treatment Practices and Barriers for Depression and Anxiety by Primary Care Advanced Practice Nurses in Wyoming

PURPOSE

The aim of this study was to investigate barriers to treatment and screening related to depression and anxiety and the diagnostic and treatment practices of primary care advanced practice nurses (APNs) in the state of Wyoming.

DATA SOURCES

Every primary care APN in Wyoming received a mailed questionnaire asking them about treatment barriers, screening and treatment practices, and attitudes toward depression and anxiety.

CONCLUSIONS

Wyoming APNs in primary care routinely identify, evaluate, and treat patients with both depression and anxiety. APNs generally felt positive about treating these patients, although they reported that their patients encounter a number of financial barriers in accessing treatment. Routine screening practices for depression and anxiety were relatively low among the APNs, and they used a wide variety of interventions for these patients.

IMPLICATIONS FOR PRACTICE

The findings identify a lack of standardized approaches to assessment, referral, and treatment, especially pharmacologic intervention, and may indicate the need for alterations in the educational preparation of primary providers in order to improve clinical outcomes of treatment for depression and anxiety.

Assessment of beliefs about psychotropic medication and psychotherapy: development of a measure for patients with anxiety disorders

OBJECTIVE

This study presents the psychometric properties of a brief measure to assess beliefs about psychotropic medications and psychotherapy among patients with anxiety disorders.

METHOD

Data were collected on a large sample of primary care patients with a range of anxiety disorders, as part of the Collaborative Care for Anxiety and Panic study. Factor analyses using principal axis factoring with Varimax rotations were used to determine the factor structure of the beliefs scale. Internal consistency, concurrent validity and predictive validity of the resulting subscales were examined.

RESULTS

Two subscales emerged, one reflecting beliefs about psychotropic medications and the other assessing beliefs about psychotherapy. Both showed strong internal consistency and concurrent validity. The beliefs about psychotropic medication demonstrated strong predictive validity.

CONCLUSIONS

This measure may be a useful tool for assessing treatment beliefs among patients with anxiety disorders toward the provision of more quality treatment for this population. Its brevity may make it particularly useful in primary health care settings.

Mental health issues within the general health care system: the challenge for nursing education in Australia

The mental health content of undergraduate nursing programs has consistently been identified as inadequate in preparing graduate nurses with the knowledge and skills for, and interest in, a career in mental health nursing. Since the introduction of generic nursing education, undergraduate programs have become primarily focused on the development of generalist skills, with specialisation occurring at postgraduate level. The integration of mental health services within the broader health care system in Australia has led to a significant increase in the prevalence of mental health problems within the general health care setting. The relevant literature suggests that nurses are not well prepared to meet the mental health care needs of this population. The aim of this paper is to briefly outline the incidence of mental health problems within the general health care system, the implications for nursing, and the potential role which nursing could play in recognising, and providing appropriate care for the treatment of mental health problems. The implications for nursing education, and the need for mental health nursing skills to be considered essential for all nurses will be discussed.

Usage and longitudinal effectiveness of a Web-based self-help cognitive behavioral therapy program for panic disorder

BACKGROUND

Anxiety disorders are common problems that result in enormous suffering and economic costs. The efficacy of Web-based self-help approaches for anxiety disorders has been demonstrated in a number of controlled trials. However, there is little data regarding the patterns of use and effectiveness of freely available Web-based interventions outside the context of controlled trials.

OBJECTIVE

To examine the use and longitudinal effectiveness of a freely available, 12-session, Web-based, cognitive behavioral therapy (CBT) program for panic disorder and agoraphobia.

METHODS

Cumulative anonymous data were analyzed from 99695 users of the Panic Center. Usage statistics for the website were examined and a longitudinal survey of self-reported symptoms for people who registered for the CBT program was conducted. The primary outcome measures were self-reported panic-attack frequency and severity at the beginning of each session (sessions 2-12).

RESULTS

Between September 1, 2002 and February 1, 2004, there were 484695 visits and 1148097 page views from 99695 users to the Panic Center. In that same time period, 1161 users registered for the CBT program. There was an extremely high attrition rate with only 12 (1.03%) out of 1161 of registered users completing the 12-week program. However, even for those who remained in the program less than 12 weeks we found statistically significant reductions (P<.002) in self-reported panic attack frequency and severity, comparing 2 weeks of data against data after 3, 6, or 8 weeks. For example, the 152 users completing only 3 sessions of the program reduced their average number of attacks per day from 1.03 (week 2) to 0.63 (week 3) (P<.001).

CONCLUSIONS

Freely available Web-based self-help will likely be associated with high attrition. However, for the highly self-selected group who stayed in the program, significant improvements were observed.

Association of tryptophan hydroxylase gene polymorphism with depression, anxiety and comorbid depression and anxiety in a population-based sample of postpartum Taiwanese women

Depression and anxiety disorders often coexist clinically and both are known to have a genetic basis, but the mode of inheritance is too complicated to be determined so far. Serotonin is the biogenic amine neurotransmitter most commonly associated with depression and anxiety. Since tryptophan hydroxylase (TPH1) is the rate-limiting enzyme in serotonin biosynthesis, its role in the pathophysiology of these psychiatric diseases has been intensively studied. In this study, we examined whether polymorphism of the TPH1 gene is related to the etiology of major depression, anxiety and comorbid depression and anxiety. Five single nucleoside polymorphisms of the TPH1 gene were studied in a population-based sample of postpartum Taiwanese women consisting of 120 subjects with depression or/and anxiety and 86 matched normal controls. A significant difference (P = 0.0107) in genotype frequency for the T27224C polymorphism was found between the comorbid and normal groups, and risk analysis showed that the C allele conferred a strong protective effect (odds ratio = 0.27; 95% confident interval = 0.11-0.7). Three-allele haplotypes involving T27224C polymorphism were constructed and haplotype associations between particular haplotype combinations and various diseases identified. However, the associations were weak and the overall haplotype frequency profiles in all groups were similar. The results suggest that depression, anxiety, and comorbid depression and anxiety disorders may have related etiologies. In addition, this study suggests that the TPH1 gene might play a role in the pathogenesis of these closely related disorders.

Empirical limits for the forensic assessment of PTSD litigants

This paper discusses the limits of expert opinion on posttraumatic stress disorder (PTSD) in personal injury claims. The construct of PTSD is hampered by several empirical limitations. Multiple reliable measures of PTSD exist, but have not been evaluated sufficiently within litigating samples and are infrequently used by forensic assessors. Common methods for trauma screening appear insensitive. Opinions about causation of PTSD and disability are complicated by retrospective memory biases, as well as the failure of most anxiety disorders to be detected within primary medical care. PTSD appears to have a steep spontaneous remission curve during the first year, but at least 10% of trauma-exposed people suffer chronic distress. Little is known about the course beyond 1 year. Efficacious psychological treatments have been developed for PTSD, but are not in common use limiting claimants' access to rehabilitative treatments. Research on functional disability associated with PTSD is in its infancy, but it seems likely that PTSD will account for only a part of the variance in work disability. We provide suggestions for improving forensic practice, advising the courts about the limitations of forensic opinions, and necessary research.

Identification of somatic and anxiety symptoms which contribute to the detection of depression in primary health care

Somatic symptoms and anxiety symptoms are often disregarded in the detection of depression in primary care. The present investigation examined to what extent somatic and anxiety symptoms recorded with the Composite International Diagnostic Interview-Primary Health Care Version (CIDI-PHC) can improve the detection of depression as compared to the General Health Questionnaire-12-item version alone. Data from the World Health Organization study on Psychological Problems in General Health Care were used. The study sample consisted of primary care attenders from 15 centres from all over the world who underwent a psychiatric examination with the CIDI-PHC. Medically unexplained somatic symptoms (back pain, feelings of heaviness/lightness in parts of the body, periods of bodily weakness, seizures/convulsions, permanent tiredness, exhaustion after a minimum of effort) and-to a smaller extent-diverse anxiety symptoms (e.g. feelings of anxiousness/nervousness, feelings of tension, difficulties relaxing) significantly contributed to the detection of depression in a logistic regression analysis. The results confirm the observation that in primary care somatic symptoms play an important role in the manifestation of depressive disorders. The items investigated herein could prove beneficial for future depression screening instruments to improve the detection of depressive disorders in primary care.

Anxiety and depression in the working population using the HAD Scale--psychometrics, prevalence and relationships with psychosocial work characteristics

BACKGROUND

The purposes of this study were: 1) to explore the psychometric properties of the HAD Scale in the working population, 2) to determine the prevalence of anxiety and depression on two severity levels among employees, and 3) to examine whether psychosocial work-related determinants for both categories of mental health problems may differ.

METHODS

Data were taken from 7482 employees participating in the epidemiological Maastricht Cohort Study on Fatigue at Work. Anxiety and depression were measured with the easy to administer self-report Hospital Anxiety and Depression (HAD) Scale, while several questionnaires and self-formulated questions were used to measure psychosocial work-related characteristics.

RESULTS

A principal component analysis indicated that the HAD Scale enables measuring anxiety and depression as separate constructs among employees. On a subclinical level, prevalences of anxiety and depression were both considerable: anxiety prevalences were 8.2 % for males and 10 % for females, and depression prevalences were 7.1% for males and 6.2% for females. Regarding self-reported psychosocial work characteristics, in multivariate regression analyses partly differential cross-sectional associations were found for anxiety and depression.

CONCLUSIONS

The results indicate that subclinical anxiety and depression are considerable in the working population and provide suggestive evidence that diagnosing, preventing or managing anxiety and depression among employees may require focusing on different aspects of their psychosocial work environment.

Prevalence of anxiety symptoms among a sample of outpatients in an internal medicine clinic: a pilot study

Previous studies in primary care settings indicate that Axis I anxiety disorders range in prevalence from 2.1% to 14.8%. However, the prevalence of anxiety symptoms, rather than Axis I diagnoses, has undergone limited study. In a pilot study, we surveyed 88 outpatients in an internal medicine clinic and explored the prevalence of various anxiety symptoms based on four measures of anxiety and worry. Thirty percent of participants endorsed mixed anxiety features, 33% reported generalized anxiety symptoms, nearly half acknowledged obsessive-compulsive personality symptoms, and nearly a quarter identified meaningful levels of worry. Seventeen percent of participants were positive on all four study measures. These data suggest that anxiety symptoms are probably more prevalent in primary care settings than recognized.

Frequency and patterns of psychiatric comorbidity in a sample of primary care patients with anxiety disorders

The current report examines the rates of psychiatric comorbidity in a sample of 539 primary care patients diagnosed with anxiety disorders using the Structured Clinical Interview for DSM-IV (SCID-IV). Though not a typical psychiatric sample, rates of comorbidity were found to be as high or higher than those reported in studies conducted in traditional mental health settings. Multiple anxiety disorders were diagnosed in over 60% of participants and over 70% of participants had more than one current axis I diagnosis. Rates of current and lifetime comorbid major depression were also very high. Patterns of diagnostic comorbidity were also examined, with significantly elevated risks for the co-occurrence of several specific pairings of disorders being found. The study results are discussed in context of a recently published, large-scale study of anxiety disorder comorbidity in psychiatric patients (Brown et al., 2001). Implications of these results for both the mental health and primary care fields are also discussed.

Mental health treatment received by primary care patients with posttraumatic stress disorder

BACKGROUND

Posttraumatic stress disorder (PTSD) is receiving growing attention as a pervasive and impairing disorder but is still undertreated. Our purpose was to describe the characteristics of mental health treatment received by primary care patients diagnosed with PTSD.

METHOD

4383 patients from 15 primary care, family practice, or internal medicine clinics were screened for anxiety symptoms using a self-report questionnaire developed for the study. Those found positive for anxiety symptoms (N = 539) were interviewed with the Structured Clinical Interview for DSM-IV. Of these patients, 197 met diagnostic criteria for PTSD and were examined in the present study regarding the rates and types of mental health treatment they were currently receiving. Data were gathered from July 1997 to May 2001.

RESULTS

Nearly half (48%) of the patients in general medical practice with PTSD were receiving no mental health treatment at the time of intake to the study. Of those receiving treatment, psychopharmacologic interventions were most common. Few patients were receiving empirically supported psychosocial interventions. Current comorbid major depressive disorder and current comorbid panic disorder with agoraphobia were significantly associated with receiving mental health treatment (major depressive disorder, p <.10; panic disorder with agoraphobia, p <.05). The most common reason patients gave for not receiving medication was the failure of physicians to recommend such treatment, which was also among the most common reasons for not receiving psychosocial treatment.

CONCLUSIONS

Despite the morbidity, psychosocial impairment, and distress associated with PTSD, substantial proportions of primary care patients with the disorder are going untreated or are receiving inadequate treatment. Results suggest a need for better identification and treatment of PTSD in the primary care setting.

Emotional disorders in primary care

Individuals with emotional disorders are more likely to use primary medical care than specialty mental health services, but these disorders are likely to be undetected or inadequately treated. Recognition of the importance of primary medical care for the treatment of mental disorder has resulted in pressing new research priorities. One set of issues concerns the adequacy of existing nosological systems for conceptualizing emotional disorder in primary care and identifying need for treatment. Another concerns the difficulties translating efficacious treatment into effective strategies that can be integrated into the competing demands of primary medical care. Psychologists have played only a limited role in defining and addressing emerging questions. Irreversible changes in mental health services have created the need for the development of a psychosocial perspective for what would otherwise be defined as narrowly biomedical issues.

Physician office visits of adults for anxiety disorders in the United States, 1985-1998

OBJECTIVE

To determine the number of physician office visits by adults in which an anxiety disorder diagnosis was recorded and rates of treatment during these visits.

DESIGN

We used data from the 1985, 1993, 1994, 1997, and 1998 National Ambulatory Medical Care Surveys, which is a nationally representative series of surveys of office-based practice employing clustered sampling.

SETTING

Office-based physician practices in the United States.

PARTICIPANTS

A systematically sampled group of office-based physicians.

RESULTS

The number of office visits with a recorded anxiety disorder diagnosis increased from 9.5 million in 1985 to 11.2 million per year in 1993-1994 and 12.3 million per year in 1997-1998, representing 1.9%, 1.6%, and 1.5% of all office visits in 1985, 1993-1994, and 1997-1998, respectively. The majority of recorded anxiety disorder diagnoses were not for specific disorders, with 70% of anxiety disorder visits to primary care physicians coded as "anxiety state, unspecified." Visits to primary care physicians accounted for 48% of all anxiety disorder visits in 1985 and 1997-1998. Treatment for anxiety was offered in over 95% of visits to psychiatrists but in only 60% of visits to primary care physicians. Primary care physicians were less likely to offer treatment for anxiety when specific anxiety disorders were diagnosed than when "anxiety state, unspecified" was diagnosed (54% vs 62% in 1997-1998). Prescriptions for medications to treat anxiety disorders increased between 1985 and 1997-1998 while use of psychotherapy decreased over the same time period in visits to both primary care physicians and psychiatrists.

CONCLUSIONS

Although there is a large number of office visits with a recorded anxiety disorder diagnosis, under-recognition and under-treatment appear to be a continuing problem, especially in the primary care sector. Medication is being substituted for psychotherapy in visits to both psychiatrists and primary care physicians over time.

Considerations in the treatment of anxiety disorders: a pharmacoeconomic review

Anxiety disorders are a group of common mental disorders that impose a significant economic burden on the healthcare system and society. For this review of published literature on the pharmacoeconomics of treating anxiety disorders, various studies of the cost, resource use and the economic outcomes of pharmacological treatment were examined. Numerous studies have been published that document how the excessive costs associated with anxiety disorders, especially panic disorder, result from a combination of factors including under-recognition and misdiagnosis of the problem by primary healthcare providers, high medical resource utilisation including unnecessary or inappropriate diagnostic tests and high levels of medical help-seeking behaviour by patients. Little information has been available on the economic effects of pharmacotherapy for anxiety disorders but recent studies have shown that selective serotonin re-uptake inhibitors (SSRIs) are associated with a shift in medical resource utilisation (lower rates of emergency department and laboratory visits) which can potentially result in decreased healthcare expenditures. Facilitating an increased awareness among primary healthcare providers of the anxiety disorders and utilising appropriate diagnostic and treatment strategies can benefit patients while providing more efficient and effective healthcare spending leading to an overall reduction in the burden of disease.

A Review of the Diagnosis, Pharmacologic Treatment, and Economic Aspects of Anxiety Disorders

As many as 1 in 4 Americans will experience an anxiety disorder at some point in their lives, and many will also suffer the depression, substance abuse, distressing physical signs, and socioeconomic problems that often accompany these disorders when left untreated. Anxiety disorders can be detected using simple screening tools in the physician's office. Early and effective treatment with appropriate medication can significantly reduce the psychic and physical symptoms of anxiety, lowering the overall costs of the disorder to the health care system and society. Many drugs offer safe and effective relief of anxiety symptoms with few side effects or drug-drug interactions, and some offer symptomatic relief within 1 to 2 weeks.

The platelet as a peripheral marker in psychiatric illness

The identification of peripheral markers of psychiatric illness is important if an improvement in the diagnosis and treatment of various diseases with overlapping symptomatology is desired. There are many disorders that not only have overlapping symptomatology, but also have similar biological disturbances. The functional capability of the neurons involved in the disease processes may be at the crux of the underlying pathology. The platelet intracellular calcium response to neurotransmitter stimulation has previously been used as a peripheral marker of psychiatric illness. This review discusses evidence in support of the extended use of the platelet as a peripheral marker. The use of the platelet intracellular calcium response to neurotransmitter stimulation as a state or trait marker in major depression, the specificity and selectivity of this response, and the possible use of the platelet as a peripheral marker in psychotic disorders such as schizophrenia, mania and psychotic depression are shown. Finally, a proposed mechanism for the association between certain psychiatric disorders and cardiovascular disease is discussed. Copyright 2001 John Wiley & Sons, Ltd.

Posttraumatic stress disorder in the primary care medical setting

Posttraumatic stress disorder (PTSD) is a prevalent disorder that adversely affects 2-5% of the general population. Little is known about PTSD in the primary care setting. The purpose of the present study was to evaluate the utility of a screening instrument for PTSD (the PCL-C) in primary care and to examine comorbidity, disability, and patterns of healthcare utilization among persons with PTSD in this setting. Adult, English-speaking patients attending for routine medical care (N=368) participated in a two-stage screening consisting of the administration of a self-report measure for posttraumatic stress disorder (the PCL-C) followed by a structured diagnostic interview. Current (1-month) prevalence of PTSD was determined, as were current comorbid disorders. Brief functional impairment and disability indices were administered, and healthcare utilization in the prior 6 months was ascertained. 11.8% (standard error 1.7%) of primary care attendees met diagnostic criteria for either full or partial PTSD. Comorbidity with major depression (61% of cases of PTSD) and generalized anxiety disorder (39%) was common, but less so with social phobia (17%) and panic disorder (6%). Substance use disorder comorbidity (22%) was also fairly common. Patients with PTSD reported significantly more functional impairment than patients without mental disorders. Patients with PTSD also made greater use of healthcare resources than not mentally ill patients. PTSD frequently is encountered in primary care, and is associated with considerable functional impairment and healthcare utilization. Comorbidity with other mood and anxiety disorders is extensive. It remains to be seen if greater awareness and more aggressive treatment of PTSD in primary care will lead to improved functioning and reduced (or more appropriate) healthcare utilization. These are topics for further study.

Psychiatric and Somatic Markers of Anxiety: Identification and Pharmacologic Treatment

Anxiety disorders are widely prevalent but insufficiently recognized and inadequately treated in primary care practice. The annual costs of morbidity and mortality of these disorders approach $50 billion, substantially more than costs for schizophrenia or all affective disorders combined. Somatization of anxiety contributes to the challenges of making an accurate diagnosis and to the indirect costs associated with delaying appropriate treatment. Pharmacologic interventions give clinicians the necessary tools to treat anxiety safely and effectively. Former therapeutic choices were limited to benzodiazepines, buspirone, and older antidepressants, but newer anxiolytic agents have become available. The selective serotonin reuptake inhibitors and agents with dual reuptake inhibition, such as venlafaxine XR, are optimizing therapy and yielding less risk for serious adverse events, greater safety in long-term therapy, and opportunity for improved patient compliance. These newer antidepressants provide substantial efficacy in patients with comorbid anxiety and depression, commonly seen in the primary care setting.

The treatment of anxiety disorders in a primary care HMO setting

Anxiety disorders are common, yet under diagnosed, in primary care settings. Many patients with anxiety and other psychiatric disorders do not seek care in mental health care settings. An integrated primary care/mental health model offers one approach to improving outcomes for patients with anxiety disorders. This model has been researched for the treatment of depression with positive results but has not been well studied for the treatment of anxiety disorders. We describe the results of care for a cohort of adult patients with Generalized Anxiety Disorder (GAD) and clinically significant anxiety secondary to Major Depressive Disorder (MDD) treated in an integrated model. Compared to a matched cohort of adults treated in a primary care setting with usual care, the intervention cohort experienced significantly improved reduction in symptoms of anxiety at 6 months. The intervention cohort also was significantly more satisfied with care.
